WRENCH.

. Application filed September This invention relates to wrenches and more particularly to wrenches of the fixed socket type and it is one object to provide a wrench of this type having a handle capable of being extended in opposite directions or to extend straight outwardly from the socket at will. i

It is a further feature of the invention to provide a wrench which may be used with satisfaction, in. places ordinarily difficult of access by wrenches of common type.

It is also a material object of the invention to provide a wrench composed essentially of two simple parts, relatively movable but non separable, and having means combined therewith whereby the handle element may be held in an adjusted position relative to the socket element.

These objects are accomplished by the novel and simple construction and combination parts hereinafter described and shown in the accompanying drawing, forming a material element of this disclosure, and in which:

Figure 1 is a perspective view showing an embodiment of the wrench with the lever disposed at a right angle to the socket to be used as a handle in its operation.

Figure 2 is a bottom plan view of the same and showing a spring pressed detent combined therewith.

Figure 3 is a side elevational view of the wrench with the handle extending axially from the socket, the handle being bent at a right angle near its outer end to provide an efficient grip.

Figure 4 is a partial side elevational and sectional View, the section being taken on line H of Figure 2, and showing in broken lines the relative position of parts when in inoperative position.

Referring in greater detail to the drawing, the numeral 10 designates the socket portion of the wrench, the same consisting of a short cylindrical body containing an opening 11 in its operative end, this opening being square, hexagonal or otherwise to suit the head of a bolt, screwhead or nut with which it may be engaged, the opening extending sufficiently into the body for that purpose.

The opposite portion of the body has formed in it an open recess 12 of considerable width and extending nearly to the socket opening, with which it communicates by a rectangular axial opening 13 bevelled at op- -21, 1927.- Serial No. 220,927.

posite sides, as-at 14, for a on apparent, t r

The upstanding elements 15 oneachside of the recess 12 have passing through them a narrow elongated transverse slot 16 receptive of a pin 17, set rigidly in the center of the cross-shaped end portion of the handle element. e I

This element consists .of a bar 18, of rectangular crosssection which may be turned at its outer end 19 at a right angle to provide an efiective grip and at its operative end is formed with opposed rectangular projections 20 and terminates in a member 21, these elements all being registerable by the pin 17 with the rectangular opening 13, into which they readily enter due to the bevelled walls 14, and which combined together substantial- 1y fills the recess 12 in such manner as to actuate the socket without lost motion ofthe handle bar 18, which may be raised at will from the position shown in Figures 1 and 4 to be reversed or topermit the bar extremity 21 to enter when the lever is extended in axial relation with the socket, as indicated by the broken lines in Figure 4.

In order to hold the bar 18 in any of its adjusted positions, it is preferable to provide an opening in the bar, parallel with the opening receptive of the pin 17, and disposed in this drilled opening is a helically coiled expansion spring 22 pressing against a hardened sphere, as a ball 23, the same moving in frictional contact with one of the walls of the recess 12, the pressure of the spring being sufficient to frictionally prevent the sliding of the socket inopportunely with reference to the handle.

From the foregoing it will be seen that an extremely simple form of wrench has been disclosed, consisting merely of a socket and operating lever, and that all of the several parts readily lend themselves to ordinary machine operations in their manufacture, therefore providing a powerful wrench of inexpensive construction, and convenient of operation.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is 1. A socket wrench comprising a cylindrical body, having an article receiving socket in one end and an open recess in its main portion, said body having a narrow elongated slot in its sides intersecting the purpose further recess at a right angle, a handle having a cross-shaped head movable within the recess, a pin fixed in said head slidable in the slot, and a detent carried by said head frictionally engageable with the sides of the recess.

2. A socket Wrench comprising a straight cylindrical body having an article receiving socket in one end and an open recess of parallel width in the other end in open communication with the socket opening, the walls of the mentioned recess having a narrow elongated slot, a handle bent at a right angle at one end and having a cross-shaped head at the other end, said head being reversibly engaged in the body recess, a pin fixed centrally in said head operatively engaged in the mentioned slot, and a spring pressed detent' in said head to frictionally engage one of the walls of the mentioned recess.

3. A socket wrench Comprising a cylindrical body, having an article receiving socket in one end and an open recess in its main portion, said body having a narrow elongated slot in its sides intersecting the recess at a right angle, a handle having a cross-shaped head movable within the recess, and a pin fixed in said head slidable in the slot.

4. A socket wrench comprising a straight cylindrical body having an article receiving socket in one end and an open recess of parallel width in the other end in open communication with the socket opening, the walls of the mentioned recess having a narrow elongated slot, a handle bent at a right angle at one end and having a cross-shaped head at the other end, said head being reversibly engaged in the body recess, and a pin fixed centrally in said head operatively engaged in the mentioned slot.

This specification signed and witnessed this twentieth day of September, 1927.
